At night, when it's pretty dark in your bedroom, place your hand on the screen of the TV and flip on the lights for about 5 seconds. Now, turn off the lights and remove your hand from the screen. Notice there is an image of your hand on the screen now. Must have to do with the Phosphers on the screen reacting to the light, causing the rest to glow in the dark, but the area underneath your hand doesn't get affected. I think it works best if you have Flourescent lighting. TRY IT!!!
